If you’ve ever had a package stolen off your doorstep, you know the feeling: a mix of sadness, confusion, and disappointment in your fellow humans. And if you’re anything like YouTuber, inventor, and former NASA engineer Mark Rober, you probably also wanted to get revenge.
After getting a notification for a package delivery that he never ended up receiving, Rober checked his security cameras and, sure enough, saw footage of a woman taking the package right off his front doorstep. When he reported it to the police, they said it wasn’t worth their time to look into.

“I just felt like something needs to be done to take a stance against dishonest punks like this,” explains Rober, who has not only built a dart board that moves to get a bullseye every time, but spent nine years designing hardware for the Curiosity rover that’s currently on Mars. “If anyone was going to make a revenge bait package and over-engineer the crap out of it, it was going to be me.”
Rober started with a sketch, then spent six months iterating on the design and doing a ton of testing. The result? Something that would definitely make you regret stealing a package off someone’s doorstep. Watch the entire video below:
